What you need to know

In Neo4j Streams Plugin version 4.1.0 we announced that the plugin would not be supported after version 4.3 of Neo4j server. Following review, we are now supporting the plugin on Neo4j Server 4.4, which is the long term support release for the Neo4j 4.x series.
The plugin will not be supported from Neo4j 5.0 onward, so this should be considered the new deprecation notice.
We recommend users not to adopt this Neo4j database plugin for new implementations, and consider migrating to the use of the Kafka Connect Neo4j Connector as a replacement.
